I always hear a noise from this power supply. And, when I turn my speaker louder, then the quality of the sound will be vary bad. I pretty sure this problem is caused by power supply

Still working


Overall other than just wear in tear the power supply is great.

Bought this power supply when I was upgrading to a new graphics card back in 2008 and it's still working away

After some time the fan started to make a whining noise, so I replaced the fan

Worked Perfect


Looking for a cheap mid watt PSU this is worth a shot. Can't say yet on the longevity, but so far so good.

Purchased for a customer that had a blown PSU in a big box retail chain purchased computer. Did the job and was easy to install

Lacks appropriate amount of SATA power connections ; No converter/adapter provided

I purchased this PSU in August 2012 and discovered today that my PC won't power on. I replaced the Coolmax power supply with a spare I had and the computer works again. I would expect just about any power supply to last more than a year and a half.

good price

fairly short life

Boat Anchor


Transferred motherboard, processor, memory and HDD to a new box, installed this power supply and plugged it in. Something inside sparked, motherboard fried. NOT a good power supply. You get what you pay for.

Works great. Very quiet. Good power.


Less than a month later the PSU is selling for two dollars less. Unfortunately, the website specified one SATA connector and four peripheral connectors. The device as received had two SATA connectors and three peripheral connectors.I was able to work...
